Mid-December, and Cambridgeshire is blanketed with snow. Detective Sergeant Manon Bradshaw tries to sleep after yet another soul-destroying Internet date - the low murmuring of her police radio her only solace. Over the airwaves come reports of a missing woman - door ajar, keys and phone left behind, a spatter of blood on the kitchen floor. Manon knows the first 72 hours are critical: you find her, or you look for a body. And as soon as she sees a picture of Edith Hind, a Cambridge post-graduate from a well-connected family, she knows this case will be big. Is Edith alive or dead? Was her 'complex love life' at the heart of her disappearance, as a senior officer tells the increasingly hungry press? And when a body is found, is it the end or only the beginning?
